Jumping Spider Robot Uses Tether for Controlled Jumps

Much of the recent research into jumping robots has used biology as an inspiration. UC Berkeley’s Tailbot, for example, uses a dinosaur-inspired actuated tail to help control its orientation while in mid-air. Other jumping species aren’t quite so lucky as to be equipped with tails, and have to find other ways of not tumbling helplessly mid-jump and face planting on landing.

One of the most prolific family of jumping animals is the jumping spider: there are something like 5,000 species around the world, and rather than building webs and just sitting around until something blunders into them, jumping spiders actively hunt their prey by using their excellent vision to spot lunch, chase it down, and pounce on it. Some jumping spiders, like the Phidippus audax pictured above, even steal lunch from other spiders (a behavior known as kleptoparasitism).

Jumping spiders might not build webs, but they can still produce silk, and they don’t like leaping into the void without a safety rope any more than you do. Before they jump, they tether themselves, and then release more silk as they fly, so that if they miss their target they can catch themselves and then climb back up to where they launched from. A few years ago, biologists took a closer look at the jumping spiders’ tether system, and realized that they used it for control as well as safety: by selectively applying tension to their safety tether, the spiders can control their pitch and make sure that they land right side up.

This combination of safety and control seems like a pretty good idea, right? So let’s teach robots to do it, too.

Video Friday: Walking on Ceilings, Cat-Inspired Legs, and Robot Grasps Tofu

The 2015 IEEE International Conference on Intelligent Robots and Systems (IROS) ends today in Hamburg, Germany, and we’ve heard that some 2,500 people attended the talks and visited the exhibit hall. That’s yooooge, as one U.S. presidential candidate would put it.

We’ve started to post some of the most interesting stuff, but there will be lots more in-depth IROS posts for you over the next several weeks. Right now we’re preparing for ROSCon, which starts tomorrow, so for Video Friday today we selected some of our favorite videos presented at the conference. Enjoy!

Honda Using Experimental New ASIMO for Disaster Response Research

During the Fukushima crisis in Japan, the lack of Japanese robots that were available to help out was notable. There was some question as to why Honda didn’t just send ASIMO (arguably one of the most sophisticated and capable humanoid robots in existence) to help out. The simple answer is that ASIMO wouldn’t be able to handle that kind (or any kind) of extreme environment. The robot was never intended to be a disaster mitigation robot; it was designed to work in offices, specifically the kind of offices that have not experienced an earthquake, explosion, alien invasion, sharknado, or other messy event. Honda is clearly aware of ASIMO’s limitations in tackling these kinds of situations, and that’s probably why (as we reported two years ago) the company has been developing a new version of ASIMO that is specifically designed for disasters.

At the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) this week, Honda engineers presented a pair of papers on research they’re doing with disaster-response humanoid robots. The researchers report that they’ve been focused on complex tasks such as gait transitions and ladder climbing. It was nice seeing that their ASIMO-based experimental humanoid is already doing some very impressive things.

Robot With Bimetal Feet Can Walk in a Frying Pan Forever

A bimetal consists of two different kinds of metal stuck together. Bimetals are different than alloys, where the two metals are blended; in a bimetal, the two metals are just layered on top of each other. The reason to do this is to take advantage of the different characteristics of different metals when they’re heated: they expand at different rates, causing your piece of bimetal to deform until it cools off again. Essentially, a bimetal is a way to convert heat directly into mechanical energy, and researchers at the University of Tokyo have come up with a way to leverage this to get a robot to walk. The robot has no sensors and no actuators, and as long as it’s got a hot surface to walk on, it can keep going pretty much forever.

Harvard's Robot Bee Is Now Also a Submarine

For the last several years, Harvard has been developing a robot bee. They’ve done some impressive work: their sub-paper-clip-sized, 100-milligram flapping-wing micro aerial vehicle is fully controllable down to a stable autonomous hover. It’s still tethered for power, and there’s no onboard autonomous control, but the robot flaps its wings and flies like an insect, which is awesome.

Tiny robotic bugs have lots of potential for search and rescue, surveillance, and exploration, but what’s been all the rage recently is adaptive multi-modal robotics: robots that can creatively handle a combination of terrains, making them much more versatile. With some exceptions, robots are usually pretty bad at this, and with some exceptions, humans and animals are too. There are ground robots that can handle water, and a few flying robots that aren’t totally helpless on the ground, but so far, we haven’t seen much in the way of flying robots that are good swimmers. 

Yesterday at IROS, Harvard researchers presented a paper describing how they managed to get their robotic bee to swim, which I’m pretty sure is not a thing that even real bees are known for doing. With no hardware modifications at all, Harvard’s RoboBee can fly through the air, crash land in the water, and turn into a little submarine. You know what that means: nowhere is safe from robot bees.

Video Friday: CableRobot Simulator, Under Ice Rover, and Robotic Optical Illusions

Tomorrow, we’re getviting on a very large airplane and taking a very long flight to Germany to cover the 2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in Hamburg. Our schedule so far includes attending 152 handpicked talks over three days, which is of course impossible, but (as we always do) we’re going to do our best anyway. There are also workshops, technical tours, keynotes, plenaries, and forums: you can see everything on the schedule here.

Since we spend all day attending sessions and checking out real robots at the exhibition (did we mention that there’s an exhibit hall, because there’s an exhibit hall), that doesn’t leave a lot of spare time or energy to sit down and, you know, write articles and stuff. We’ll do our best to get you some selected highlights every day, and we’ll definitely be reporting on IROS for the next several weeks.

Oh, and if you’re going to be at IROS, make sure and say hi: I’ll be the exhausted looking guy with an oversized camera trying to see everything at once.

Rethink Robotics' Sawyer Goes on Sale, Rodney Brooks Says 'There May Be More Robots'

“Everything is a mess,” Rodney Brooks says, as we make our way through a brick-walled room filled with robots in various states of assembly here at Rethink Robotics’ headquarters in Boston, Mass. The mess, we should point out, makes Brooks, the company’s founder and CTO, very happy. It means things are busy. The past few weeks, he says, have been particularly hectic. That’s because today Rethink is making its collaborative factory robot Sawyer available for purchase.

Robot Shows How Babies Are Actively Plotting to Make You Smile

Sometimes, babies like to smile. Perhaps you’ve noticed this. Sometimes, they smile because they’re happy, but a lot of the time, they’re smiling primarily because they want you to smile, and they’re doing it using “sophisticated timing” to manipulate you into obeying them. 

Researchers from Olin College, the University of Miami, and UC San Diego have been studying baby smile schemes, and to test their hypotheses, they’ve used a slightly uncanny robot baby to smile at undergrads who probably had no idea what they were signing up for.

Clearpath's OTTO Robot Can Autonomously Haul a Ton of Stuff

Today, Clearpath Robotics (best known for its rugged, ROS-friendly, and infallibly black and yellow robotic platforms) is announcing OTTO, a “heavy-load material transporter” that can carry a ton of stuff around warehouses, fully autonomously. Actually, “a ton of stuff” is underselling OTTO’s capabilities, since it can happily roll away with one metric ton and a half of payload: that’s a staggering 1500 kilograms (3300 pounds), or more than 22 robotics bloggers. Oof.

Trash Hauling Robots Are Cool, But Do We Really Need Them?

Volvo Group is partnering with Chalmers University of Technology and Mälardalen University in Sweden, Penn State University, and Renova (a Swedish waste recycling company) to “develop a robot that interacts with the refuse truck and its driver to accomplish the work.” The concept image above shows some mobile manipulators capable of lifting heavy loads and dynamically navigating (and balancing) in an unstructured environment. 

If Volvo can pull this off, it would be pretty amazing. But at this point, we’ve got two questions: is it something we need, and is it realistic?
